No, that 90 is very different. The 50-140 isolates similar but has a more painterly line draw to it. That 90 is bitingly sharp, not sterile looking though. The bokeh on that 90 is like an airbrush. The 50-140 is more like pastels. I don't look at the flickr page anymore, just gets my GAS flared up. I could literally street shoot with that 90 and be like a kid in a candy store. Oh, no, my wallet is quivering.
